Huygens wave theory:
Huygen's wave theory is not correct in all respects.
2. It assumes simply that light energy is propagated as a wave.3. At the time of his proposition Huygen's did not have any idea about wavelength or about the transverse nature of light.4. So Huygens wave theory was Later modified by Thomas Young and Fresnel.5. They introduced the concept of wavelength and assumed that light waves are transverse.6. By these assumptions they could successfully explain not only the rectilinear propagation of light but also the phenomena of interference, diffraction and polarization of light.
A small bucket of mass M kg is attached to a long inextensible cord of length L m. The bucket is released when the cord is in horizontal position. At its lowest point the bucket sc
Capacitors in parallel: Three capacitors are connected in parallel. If on closing the switch S a current I flows in the circuit, then from Kirchoff's first law:
examples of unlike parallel forces
A circular hole of radius r at the bottom of an initially full water container is sealed by a ball of mass m and radius R (>r). The depth of the water is now slowly decr
Q. Illustrate that water drain counter clockwise in the northern hemisphere and clockwise in the southern hemisphere? Answer:- This isn't a myth. It drains counter clockwi
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
How CPH takes spin and converts to graviton? Answer- A CPH Principle says a CPH moves with constant speed as Vc, Vc>c in any inertial frame and any space, therefore that
